Be it known that I, Lro F.

Improvements in Eyeglasses;

by declare the following to be a full, clear,

and exact description ofthe same, reference being the reference-numerals marked thereon.

My present invention relates to optics and more particularly to eyeglasses and eyeglass g mountings and 1t has for its object to provide an improved mounting of'the finger piece 4type in which ajrm bearing is provided for theguard lever and all of the pai-tee are held securely in definite positions While 2.

at'j, -.tlie same .time the parts may be readily and easily assembled and detached.

'i The improvements are further directed tosimple and lconvenient Ward providing a means for varying .that positions the the tension of the spring the 4novel feat-ures claims at the endof the specification.

Anr,of Albany, in the county of Albany and State of NeWr have invented certain new and useful and I do herehad Ato the accompanying drawings,` forming a part ofthis specification, and toi guard and to these and-l other ends the-inventionl consists incertain; improvements and combinations of parts all as :will be hereinafter more fully described,f being pointed out in the;

fastenerll on the o ng portion 1, lens atl embodying the edge 'hearngearslend' attaching ears 4 through i passed, and inter-ii mediate connecting portions 6 that formthe each guard into spaced upper and lower tionsfernung the upper and lower Wal s of sired type, being formed in the present instance of fiat stockwith a depending finger portionl 8 at the forward end and nose engaging portions 9 at the rear end.-

The connecting portions or supports 6 are, A inthe present instance, provided with substantially horizontally extending pocket-S10 that are preferably open at the front and rear only and that divide the support for the pocket. An., aperturell extending vertically through Vthe support.'passsitliough both vv'alls of this pocket'and preferably at 4the rear edge of one Wall are provided a plurality of abutments 12 formingserrations in said'edge. "i

Each guardi 7 turns, Iin thev present in'- stance, on the tahlelafforded at the top side of the support 6 "and, is provided with a preferably Iintegral or iixedly connected pivoting member 13 that projects laterally therefrom and forms an elongated bearing member turningfin .the yaperture 1 1 and, being carried by the guard' lever, is removable therewith. The lower orl outerendof this pivoting member is engaged'v by adjetachable v positeside of the support from thelever and 1 prefer to make the pivoting member 13 hollow or tubular s o that i t is`in the-natureof a sleeve and to provide, ,as the fastener 14, a screw threaded into the' sleeve and I'havingitsrshoulder 15 coperating with theunder'faoeoi the sup7 port and with `the {end 'faceofjthe sleeve, both of these facesbeing inthe same plane.

The springlfor positioning each guard, is located Withinthe pocket 10'and is held in place bylthilpivoting member 13 about whichit isfoiled though it 'may be inserted and withdrawn, when the ivotin'g-inembei` and guard are removed om oneof the open sides of' the pocket, preferably the rearone .j1.'v1`he spring has-an adjustable stance the support,':for which Vpurposetnae end of the spring has a downwardly extendiing arm 17 that coperates with the abutiso - connection with one 'of the parts, in this'in- As before indicated, the present mounting g is of the finger piece type'and comprises a "-preferablyrigid brd roo' ments 12, while' an arni 18 at the. other endy crate withthe ard7. The tension of sp is'v'ari f according to the particular amenant 12'with which thearmrz is eng.

gag'ed,asvvill be underatood.y

:'"th'rea-d'ed engagement of the the pivoting inember is so distributed be?- cause of the length of the latter that there .from the guard nos lwith v I guard lever mounted to turn on one `side,

own e asticity in alinement with theaper-` ture 11 and with its arm 17 in engagement with one or another of the 'abutments 12. The guard` is next applied, its pivoting member 13 being readily thrust aperture 11 and through the springv because of the facility ai'iiorded its manipulation of the pivot due to the,V attachment to the guard. When the vother armr 18 of the spring is next hooked over the guard lever the`la't'ter is `placed und'ei'tension and it remainsl only to apply the fastener -,let from the bottom.

It'Will be further lobserved Ythat `a long bearing: .is providedjforf-the guard, the `Whole length of the member .13 being utito'prevent theguard from tilting, While the support-is gripped between the guard and the head of the fastener 111 with is per- 'uard '-.to Furt er, the fastener with bind 1n its movements.

is no danger of stripping the threads and, in fact, this threaded portion of the fastener may vbe runy entirely through the guard as Wellv as through the sleeve, as

shown. v

In Fig. 7 I show that the tubular pivoting member vl'fmay be formedseparate and detachable from both it and "the support, in which case it is pro- ",vided with a head 19 that bears on the top side ofy the guard so that the guard may turnrelativel-y toit or it may turn in the A support with the guard.
